Nation Grinding, Inc. retrofits, rebuilds, and/or repairs hard surfaced wire drawing blocks or capstans and we are recognize as a leader in this industry. The cutting edge with HVOF, Plasma Metalizing Technology is used to improve wear and corrosion resistance. HVOF (high velocity oxygen fuel) is a hard surfacing process where alloy powder is expelled from a spray gun at speeds that exceed MACH 6. The powder impinges on the substrate and then builds up. A wide variety of alloys can be applied with the HVOF System. Many parts include sheaves, rolls, and wire guiding devices. Custom coatings are used to restore worn metal surfaces.
